Abstract
The fire propagation performance and the physical and mechanical properties of commercial chipboard treated with fire retardants at the rate of 10, 15 and 20 % of the weight of dry chips have been evaluated. The incorporation of fire retardants, monoammonium phosphate (MAP), boric acid (BA) and borax (BX) improved the fire propagation performance of the board. Treatment with MAP and BA at the rate of 20 % by weight of the dried chips improved the propagation values, I, by more than 50%. The values were less than 25 and qualified for the surface spread rating of class 1. The propagation sub-index, i,, for all treatments was less than 6. BA, MAP and BX reduced the modulus of rupture (MOR) and tensile strength of chipboard. Incorporation of chipboard at 10 to 20 % of weight of dry chips did not enhance the hygroscopicity and water adsorption of chipboard. Chipboards incorporated with 10% BX, 15% BA or 20% MAP satisfied the requirements for Type 1 (Standard) board stipulated in the B.S. 5669.
